Oracle as a company are cowardly and rude and the practicalities are simply an excuse. There's clearly one "better way" which is to put a name at the end of the email, for perhaps Larry himself to take responsibility as he should.
If anything the practicalities show how arbitrary the decision was. Checking the Oracle subreddit we got people with "exceeds expectations" as their average still getting culled. It would appear how they decided upon the cuts reflects on how they have performed them. With all the sophistication of a child in a candy shop trying to buy more candy than their piggy bank can afford and then just dropping the excess on the floor, walking away and trying to forget that it ever happened.
